Exterior Rigid Insulation - What are our actual sustainable product options?

Scott - Thank you for initiating a great thread. In CA rigid foam is prescriptively required on low-rise residential buildings unless you complete your thermal analysis on a performance basis. Also, while T-stud makes sense to lessen the thermal bridge, you can go even further by using BamCore’s Prime Wall which can eliminate over 90% of the thermal (and acoustical) bridging while also eliminating gypsum and OSB.
